To all whom it may concern:

Be it known that I, FRANK H. STANARD, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

This invention comprehends the provision of a hydrocarbon burner, wherein the vaporizing chamber is positioned between the outlet openings thereof, and consequently subjected to the maximum degree of heat intensity, with a view of both hastening vaporization of the fuel and producing a high quality of combustible mixture when dis charged from the mixing chamber.

In carrying out my invention I provide a burner with an interiorly disposed chamber communicating with the vaporizing chamber for the storage of generated gas, and provided with a valve controlled outlet whereby the burner is always maintained in a primed condition for instantaneous use when desired.

Another important object of the invention consists in the provision of a single casting constituting the burner proper, and which embodies the vaporizing, storage and mixing chambers respectively, the latter being defined by a construction which tends to effectively battle the air and gaseous vapor, thus affording the requisite degree of time in the production of a high quality of combustible mixture.

With my improved construction I propose to separate from the gas, in the storage chamber all the carbon that may be made and carried into the storage chamber from the vaporizing chamber, with a provision of means for relieving the storage chamber of such carbon and dust or other foreign matter as the occasion may require.

- It is also the object of this invention to provide a connection between the main burner, and one or more auxiliary burners, whereby the burners may be put into use separately or simultaneously The nature and advantages of the invention will be better understood from the following description, when read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as fall w h n th ope of What is Claimed In the drawings forming part of this specification like numerals of reference indicate similar parts in the several views and wherein Figure 1 is an elevation of the burner constructed in accordance with my invention.

Fig. 2 is a vertical sectional View therethrough.

Fig. 3 is a top. plan view.

Fig. 4 is a horizontal sectional view taken on line a-a of Fig. 1.

Fig. 5 is a similar view taken on line 6-?) of Fig. 1.

Fig. 6 is a view showing the connection between two burners.

Referring more particularly to the drawings in detail 10 indicates a base from which rises a relatively short wall 11, and disposed immediately above this wall is an oil receiving trough 12 projecting laterally from and concentrically about the ring 13, the latter having its lower edge resting upon the base 10 inwardly of the wall 11, and projecting an appreciable distance thereabove. Resting upon the ring 13 is a member 14, which constitutes a support for the burner proper indicated generally at A.

The burner includes a top wall 15 and an annular depending wall 16, the latter being formed with vertical corrugations 17, and a circumferentially disposed corrugation 18 at its point of juncture with the top wall 15. The vertical corrugations have a plurality of slits or openings 19 while the corrugations 18 is provided with similar openings 20 for the escape of the generated gas at which points the latter is consumed. The burner proper is a single casting, embodying in its make-up, a main vaporizing passage 21, a storage chamber for the generated gas indicated at 22, and a mixing chamber indicated at 23 and partly defined by the con struction of the member 1 1 and its relative association with the burner A.

The member lt defines an inclosure 24: by the intervening space therebetween, the base 10 and the ring 13, and further includes a vertically disposed annular wall 25 rising therefrom and a top wall 26. This construction defines the main portion of the mixing chamber 23 which communicates with the inclosure 24!: through the medium of an elbow 27 having its major portion disposed within the inclosure 24, one end of the elbow entering the main portion of the mixing chamber through a suitable opening provided in the base of the member 14. The wall of thisopening is interiorly threaded, the threads of which engage the threads on the adjacent end of the elbow, by means of which construction the elbow is held in proper position. The top wall 26 of the member 14 is both inclined and curved downwardly toward the center of its base and terminates an appreciable distance above said base. As herein shown the storage chamber for the generated gas is disposed immediately beneath the top wall 15 of the burner centrally thereof, and has its bottom 28 correspondingly formed with respect to the wall 26 of the member 14 and spaced therefrom to provide what is termed a secondary mixing chamber 23 which encircles the member 14 for communication with the outlet openings 19 and 20 respectively of the burner. Both the walls 26 and 28 are provided with centrally disposed alined openings, the opening in the wall 26 establishing communication between the main mixing chamber 23 and the above referred to secondary mixing chamber 23, while the opening in the wall 28 has fitted therein a hollow tubing 29 having one end lying flush with the upper edge of the opening, while the lower end of the tube is supported upon the base of the member 14 and closed thereby. The purpose of this tube will be hereinafter more fully described.

The burner A is further provided with an offset depending neck portion 30, which establishes communication between the storage chamber 22 and the inclosure 24, and which communication is controlled by means of a needle valve 31' operatively positioned within a valve casing 32, the casing being located between the lower end of the neck 30 and the wall 11 with which the casing is connected, the valve opening within the inosure 24 in direct alinement with the ad-- source of supply and provided with a valve.

34 at a point in its length. One end of the pipe is coupled to the adjacent end of a steel tubing positioned within the neckportion 30, which tubing is indicated at 35 and as herein shown extends upwardly within the neck portion 30 surrounding the burner within the vaporizing passage 21, and having its free end opening within the storage chamber 22. Leading from said chamber is a second tubing 36 which also extends through the neck portion 30 and has its lower end suitably connected with the nipple 37 rising from the valve casing 32, and through which tubing the gas is conveyed and vaporized, the gaseous vapor. being dis-V charged into the storage chamber 22, from whence it passes through the tubing 36 into the inclosure 24. The introduction of the gaseous vapor into thechamber 24 is controlled through the medium of the needle valve 31, the gaseous vapor entering the inclosure in the form of a jet which serves to draw into the inclosure the requisite amount of oxygen through the opening 38 in the wall 16, which opening extends beyond the opposite sides of the neck portion 30. As hereinabove stated the valve 31 is disposed in direct alinement with the adjacent end of the elbow 27 which latter receives both the gaseous vapor and air, and conveys the same into the main mixing chamber 23. The formation of the top Wall 26 of this chamber is such as to deflect the mixture downwardly, so that the gaseous vapor will commingle freely with the air in the mixing chamber to produce .a highly combustible mixture. capes through theopening in the wall 26 into the secondary mixing chamber 23, which connnunicates with the outlet openings of the burner. It will thus be seen that the gaseous vapor and air are again effectively mixed within the secondary mixing chamber prior to their escape through the openings in the burner at which point the fuel is consumed. i

It will now be noted that the vaporizing passage is interposed between the openings 19 and the openings 20 of the burner, so that when the burner is put into operation the flamesfrom the openings 19 and 20 respectively practically envelop the vaporizing passage, thereby subjecting the latter to a maximum degree of heat intensity, which not only hastens the vaporization of the liquid fuel, but serves to produce a high quality of vapor which will commingle freely with the air in the mixing chamber and thus afford a high quality gas. While the burner is in operation the valve 34 re mains open admitting the introduction of the liquid fuel, it being borne in mind that the consumption of the gas is controlled by the needle valve 31. In consideration of this fact it is clear that more gas can be generated than is required for immediate use, and this excessive quantity of gas is stored within the chamber 22, thereby priming the Manifestly, as the oil is Themixture then esburner for instantaneous operation. at any time desired. It is of course to be understood that whenever the valve 31 is closed thereby cutting off the gas, the valve 34 is also closed.

Again it will be noted that the storage chamber 22 as well as the vaporizing passage 21 is located within the heating zone of the burner, with the consequence that upon initial starting of the burner, the gas contained within the chamber 22 is heated to a very high degree, thereby properly preparing the stored gas for mixture with the air upon entrance into the mixing chamber.

' By reason of the fact that the gaseous vapor is retained an appreciable length of time within the chamber 22, the carbon and dust are separated from the vapor and settle down to the bottom of the chamber, entering the tubing 29, which latter can be readily cleaned when desired by simply removing the burner proper from its support. hen so removed access may be had to the different mixing chambers for the purpose of cleansing the same.

As shown in Fig. 6 one or more burners may be coupled together, and as shown in this instance the base 38 of the burner indicated at B is a continuation of the base 10 hereinabove referred to. Rising from the base 38 is a circular wall 39 which embraces the depending wall 40 of the mixing chamber C, the wall 10 resting upon the base 88. The mixing chamber in this instance includes a bottom 41, wall 42 and a top 43, the bottom 41 being provided with an opening surrounded by a nipple 45 which establishes communication between the air duct 46 and the mixing chamber proper. Leading from the valve casing 32 of the burner A is a gas supply pipe 47 coupled in any suitable manner as at 48 to the valve casing 49 of the valve 50 associated with the burner B. Manifestly the gas generated in the burner A is fed through the pipe 17 to the valve 50, which latter controls its admittance into the space beneath the mixing chamber of the burner B. The gas then passes into the mixing chamber wherein it is permitted ample time to freely commingle with the air in the production of a highly combustible mixture. The mixture is permitted to escape from the mixing chamber through an opening 51 in the top wall 43 into the chamber 52 which latter communicates with the openings 53 in the burner proper. Depending from the opening 51 is a nipple 54 which extends a slight distance below the upper edge of the nipple 45 thereby causing the gaseous vapor to take a circuitous passage in its escape through the opening 51.

It will also be noted that the burner proper is removably supported upon a ledge 55 surrounding the base 41 of the mixing chamber, whereby the burner may be removed for the purpose of cleansing the same when desired.

While it is believed that from the foregoing description the nature and advantages of the invention will be apparent, I desire to have it understood that I do not limit myself to the precise construction and ar rangement of parts herein illustrated and described, as various changes in this respect may be resorted to when desired as fall within the scope of what is claimed.
